Yeah

The piston are to slow. I tried a 3/4" bore, 4" stroke piston (fairly small) and it wasn't quick enough.

The paddle might work somewhat but it also might lift the ball so it bounces instead of of rolls. I would prefer a straight out linear quick 4-6" movement instead of any rotational force.

Creating sometype of spring system might work but if you got that much force and speed they might think it is dangerous.

To see what my thoughts are first take a pole or plate and use it like a pool stick or a plate evenly moving out at about 6"-7" inches off the ground (mid-ball). After you've done this hold it perpendicular to the ground, make a pivot point with one hand and rotate the bar and hit the ball. If is too easy to ride up on a ball or get one stuck in the mechanism. As you change the angle of the mechanism you'll hit the ground, ride up on the ball, or make the ball fly.

The reason this is my dream robot is because it take care of these problems but I can figure a good way to make it happen.

Great in concept hard to implement. But that's engineering sometimes.
